TITLE:
Dissolving lollipops
Problem Scenario
I am trying to see if lollipops will dissolve in salt water, sugar water or, regular water faster.
Broad Question
What are the impacts of additives when dissolving hard candy in a liquid?Specific Question
What are the impacts of additives when dissolving lollipops in salt water, sugar water, and regular water?
Hypothesis:
The Dum-Dums will dissolve in the following order; salt water, regular water, and then sugar water. The lollipop will dissolve in the salt water (sodium chloride) first because salt is known to melt ice and other various substances. The sugar won't make the lollipops dissolve very fast because the lollipops contain a lot of sugar. Sugar dissolving sugar doesn't make sense. Therefore that leaves the lollipop in the regular water dissolving in between the lollipops dissolving in salt and sugar waters.Graph of Hypothesis
Variables:
Independent Variable:
Lollipops
Dependent Variable:
Time
Controlled Variable:
Regular water
Vocabulary List That Needs Explanation
General Plan :
I need to go to the store and buy a bag of Dum-Dum Lollipops and a gallon of water. I will fill up three glasses with 3/4 of water. Next I will put a tablespoon of salt in one glass, label and a tablespoon of sugar in another and label. I am going to leave one glass of water plain to be the controlled variable. The next step is to cut the sticks of the lollipops and then put one lollipop in each glass. I am putting the same flavor in each glass, so there aren't too many variables being changed. I need to label each glass so I know which one dissolves first, second and third. I will use the stopwatch on my iPod to time them as they dissolve, while keeping an eye on them. I will lap the stopwatch each time a lollipop dissolves. Next I will analyze and graph the data. When everything is done I will put everything together and buy supplies for the poster. When my poster, wiki and notebook are complete I will practice presenting my project for the KMS Science Fair and the MWV Science Fair.Potential Problems And Solutions
The problem(s) could be; Two lollipops dissolving at almost the same time.
The solution(s) could be; Retrying the experiment and seeing if the results happen to change.
Safety Or Environmental Concerns
I really don't have any safety OR environmental concerns.There aren't many things that could go dangerously wrong while dissolving lollipops in salt, sugar, and regular water.
Experimental Design
Comparative Study:
Number Of Comparison Categories:
There are 3 comparison categories in my experiment.Number of Comparison Samples:

Regular- Water is getting more orange
Sugar- A little orange at the bottom of the glass
23 minutes:
Salt- Dissolving slowly on top by the stem
Regular- Water is getting more orange by the bottom
Sugar- Bottom of the glass is orange
35 minutes:
Salt- Almost half of the lollipop is dissolved
Regular- Lollipop is dissolving
Sugar- Lollipop is dissolving slower than the others
38 minutes:
Salt- Dissolving

Sugar- Unexpectedly sped up near the end
Sugar completly dissolved in - 1:39:00
Regular completly dissolved in - 1:43:00
Salt completly dissolved in - 1:58:00
I am surprised that they dissolved so close in time.
They dissolved in almost the exact opposite order that I thought they would.
I thought they would dissolve in this order:
Salt
Regular
Sugar

Sugar- Almost identical to the lollipop in the regular water
1 hour, 12 minutes
Salt- Really catching up to the others but is still the biggest
Regular- The smallest but the sugar is almost exactly the same size
Sugar- Almost as small as the regular
Time it took for them to completly dissolve:
Sugar- 1:34
Regular- 1:46
Salt- 2:13
For this experiment I used orange flavored lollipops and 1 tablespoon of salt in one glass and 1 tablespoon of sugar in another glass. I also cut the sticks off up to the end of the lollipops.
Graphs
Results
Order they dissolved in both times:
Sugar
Regular
Salt
Conclusion:
My hypothesis stated that the lollipops would dissolve in the following order; salt water, regular water and then sugar water. The lollipop will dissolve in the salt water (sodium chloride) first because salt is known to melt ice and various substances. The sugar won't make it dissolve very fast because the lollipops contain a lot of sugar. Sugar dissolving sugar doesn't make sense. Therefor; the regular water would dissolve the lollipop in between the salt and the sugar water. My hypothesis was wrong.
I tried the experiment two times and the observations were almost the same both times. They dissolved in this order: Sugar water, regular water, and then salt water. It was exactly the opposite of what I thought. In the first trial, the lollipop in the sugar water dissolved in 1 hour and 39 minutes. The lollipop in the regular water dissolved in 1 hour and 43 minutes and the lollipop in the salt water dissolved in 1 hour and 58 minutes.
In the second trial they dissolved in the same order but different times. The lollipop in the sugar water dissolved in 1 hour and 34 minutes. The lollipop in the regular water dissolved in 1 hour and 46 minutes. Slowest of them all, the lollipop in the salt water dissolved in 2 hours 13 minutes. I am surprised they dissolved so close together. I thought they would have dissolved further apart.
Both times the lollipops completly dissolved in this order; sugar water, regular water, and then salt water.
Discussion
I am surprised they dissolved in the order they did because about 8 people including myself agreed we thought the lollipop
in the salt water would dissolve first. Instead it dissolved last, both times.
Benefit to Community and/or Science
My project was a benefit to science because it proved what substance dissolves hard candies the fastest.
Background Research:
I originally looked up the nutrition facts for the Dum-Dum lollipops. I decided I didn't trust the information from the internet. I thought it would be a little more logical to use an actual bag from the lollipops and copy the information onto the wiki page! I had already thrown mine away so I got one from a friend.
I would never use Wikipedia to get any important information but I did use it to make a list of flavors Dum-Dum lollipops. It really wouldn't affect my experiment just using it to look up flavors. I know most of the flavors definitely exist from memory. I trusted it with the years they were originated. I had a vague idea of what a data analysis and raw data were but just to make sure I was correct. I also looked the deffinetion of abstract and a few other scientific words.
References:
www.en.wikipedia.org/wiki/Dum-Dum_pop I only used wikipedia to see what flavors Dum-Dum lollipops come in.

Abstract
The problem was figuring out which flavored water dissolves a Dum-Dum lollipop quicker; salt water, regular water or sugar water. My hypothesis was;
The Dum-Dums will dissolve in the following order; salt water, regular water, and then sugar water. The lollipop will dissolve in the salt water (sodium chloride) first because salt is known to melt ice and other various substances. The sugar won't make the lollipops dissolve very fast because the lollipops contain a lot of sugar. Sugar dissolving sugar doesn't make sense. Therefore that leaves the lollipop in the regular water dissolving in between the lollipops dissolving in salt and sugar waters.
I put glasses on the counter-filled them with 3/4 cup of water, made labels, added 1tsp. of salt in one and 1 tsp. of sugar in another, leaving one plain. I cut the sticks off 3 orange lollipops and put 1 in each glass. I timed how long it took for them to dissolve with a stopwatch.
The lollipop in the sugar water dissolved before the others. Next the regular water and last the lollipop in the salt water.
My hypothesis stated that the lollipops would dissolve in the following order; salt water, regular water and then sugar water. The lollipop will dissolve in the salt water (sodium chloride) first because salt is known to melt ice and various substances.

I tried the experiment two times and the observations were almost the same both times. They dissolved in this order: Sugar water, regular water, and then salt water. It was exactly the opposite of what I thought. In the first trial, the lollipop in the sugar water dissolved in 1 hour and 39 minutes.

Both times the lollipops completly dissolved in this order; sugar water, regular water, and then salt water.
